Capable of being appraised, judged, or evaluated.
From appraise (from Old French aprisier, to set a price) plus -able. The root comes from Latin pretiare (to price), related to pretium (price).
Not everything appraisable has a price tag—your character, your effort, a painting's historical value are all appraisable even though they're not bought or sold. The word means 'capable of being evaluated,' not 'capable of being sold.'
